The control blade expansion device of the long wind power generating set of this change oar comprises track-type facilities and control telescopic element, this track-type facilities comprises fixed block and moving part, this fixed block and described wheel hub are fixedly connected, this moving part and described blade are fixedly connected, described control telescopic element is connected with moving part with fixed block respectively, and described control telescopic element drives this moving part with respect to the fixation locus back and forth movement of this fixed block along the blade central axial direction.
The track-type facilities of the long wind power generating set of this change oar is extension sleeve, and described fixed block is an inner sleeve, and described moving part is the outer sleeve that is set on the inner sleeve.
The control telescopic element of this wind power generating set is a fluid pressure drive device, and this fluid pressure drive device is connected with described outer sleeve by hydraulic rod.
The control telescopic element of this wind power generating set can also be Vidacare corp or mechanical actuation device.
Adopted the long wind power generating set of change oar of this model utility, because it adopts the simple relatively may command expansion device of structure, to decide the long wind power generating set of oar and develop into the long wind power generating set of change oar, realized not reducing Security and improved the purpose of wind power generating set power generation performance, thereby enlarged the accommodation of wind power generating set; In addition, the utility model not only can be used for the wind power generating set newly made, also can transform the wind power generating set that has put into operation.
